Detailed Description

Class representing matricies with 4 rows, and 4 columns.

CSIBCMatrix44d objects represent matricies, and define a set of operations which are useful in the context of a matrix.

This class uses double precision floating point numbers to store element values. There exists three other matrix classes, CSIBCMatrix4x4, CSIBCMatrix33d and CSIBCMatrixMNd. They are used to represent 4x4 matricies with single precision floating-point numbers, 3x3 matricies with double precision floating-point numbers, and MxN matricies with double precision floating-point numbers, respectively.

bool AreAlmostEqual ( const CSIBCMatrix44d &  in_mat1,
const CSIBCMatrix44d &  in_mat2,
const double  in_dEpsilon = PICO_EPS  
) [friend]

Determines whether all corresponding elements of the matricies in_mat1 and in_mat2 are equal. Since this method uses floating-point comparison, a threshhold value of in_dEpsilon is used for equality comparison.

Parameters:
in_mat1  First matrix for equality comparison.
in_mat2  Second matrix for equality comparison.
in_dEpsilon  Floating-point comparison error range. Defaults to PICO_EPS.
Returns:
bool true if the matricies are equal, false otherwise.
